.SH DESCRIPTION
.sp
.LP
The \fBputq()\fR function is used to put messages on a driver's queue after the
module's put routine has finished processing the message. The message is placed
after any other messages of the same priority, and flow control parameters are
updated. If \fBQNOENB\fR is not set, the service routine is enabled. If no
other processing is done, \fBputq()\fR can be used as the module's put routine.
.SH RETURN VALUES
.sp
.LP
The \fBputq()\fR function returns \fB1\fR on success and \fB0\fR on failure.
.sp
.LP
Upon failure, the caller should call \fBfreemsg\fR(9F) to free the pointer to
the message block.
.SH CONTEXT
.sp
.LP
The \fBputq()\fR function can be called from user, interrupt, or kernel
context.
.SH EXAMPLES
.sp
.LP
See the \fBdatamsg\fR(9F) function page for an example of \fBputq()\fR.
